Delete bulbs or will they re-add with device discovery? (ZHA)

Hi Folks,
So, it looks like I’ll need to re-add everything after switching channels as I’ve tried to restore from backup with no luck.
All os the devices are still listed in the HA ZHA page. If I simply try to re-pair them will they be added back to their original names and areas?
Or do I need to delete all of the devices and then start fresh?

Easy enough to try (before deleting anything). I’d think the re-paring should work, but I’ve not (yet [g]) put myself in your specific situation.

Yes.

And yes you need to re-pair everything if you change the channel.

ok, so I did need to repair everything but the configuration was remembered even after resetting the radio so there must be some lookup that doesn’t get reset. All of the lights and sensors were remembered but none of their areas were remembered.

That’s annoying. They are remembered when using Zigbee2MQTT.
